Welcome to Ms. Sophia's teacher page!

About Me

My name is Sophia Papaefthimiou (the students call me Ms. Sophia) and I'm so excited to start my 15th year of teaching! I was born in Farmington Hills, Michigan and also spent three of my early years living in Athens, Greece, where my parents were born and raised. I earned my Bachelor of Science degree in Engineering from the University of Michigan. After university, I worked at Oliver Wyman in risk management and financial services consulting. After a few years, I decided to switch careers and embark on my teaching journey. I went back to school and earned my mathematics teaching certificate from Northwestern University. I have taught Algebra, Geometry, and DP Mathematics for the last fourteen years and was also a founding teacher at Back of the Yards College Preparatory High School.

My husband and I have two daughters, Elektra (8 years) and Melina (5.5 years). When I am not teaching Math, I stay busy by spending lots of time with my family. I also love to cook, run, travel, and watch college football (Go Blue)!

This school year I will be teaching DP Mathematics: Applications and Interpretation years 1 and 2 to juniors and seniors. I can't wait to support my seniors, whom I taught last year (and some during their freshman year in Algebra), and to become acquainted with my juniors.

About 11th Grade: DP Mathematics: Applications and Interpretation SL (Year 1)

This course recognizes the increasing role that mathematics and technology play in a diverse range of fields in a data-rich world. As such, it emphasizes the meaning of mathematics in context by focusing on topics that are often used in applications or in mathematical modeling. To give this understanding a firm base, this course also includes topics that are traditionally part of a pre-university mathematics course such as calculus and statistics. This course makes extensive use of technology to allow students to explore and construct mathematical models. Mathematics: Applications and Interpretation will develop mathematical thinking, often in the context of a practical problem and using technology to justify conjectures.

The following units and topics will be covered this year:

Quarter 1:

Unit 1: Dividing up Space: Coordinate Geometry, Lines, and Voronoi Diagrams

Unit 2: Unit 2: Arithmetic and Geometric Sequences and Finance

· Rounding and Significant Figures

· Coordinate Geometry

· Equations of Lines

· Voronoi Diagrams

· Arithmetic and Geometric Sequences and Series

· Financial Applications

Quarter 2:

Unit 3: Modeling Relationships with Functions

· Exponential Functions

· Quadratic Functions

· Cubic Functions

· Polynomial Functions

· Logarithmic Functions

Quarter 3:

Unit 4: Modeling Periodic Phenomena

· Trigonometric Functions

· Right Angled Trigonometry

· Non-Right Angled Trigonometry

· Periodic Functions

· Sinusoidal Functions

Quarter 4:

Unit 5: Measuring and Representing Space: 2D & 3D Geometry

· 3D Geometry

· Area

· Volume
